  • −Entry-level endurance rating
The Kingston A400 SSD is the affordable upgrade path for anyone still running an older laptop or desktop with a traditional spinning hard drive. The performance improvement from HDD to SSD is one of the most dramatic upgrades available for aging computers — boot times drop from minutes to seconds, applications launch instantly, and overall system responsiveness transforms completely. The A400 delivers read speeds up to 500MB/s versus the 100-150MB/s typical of mechanical drives. No moving parts means no susceptibility to the shock damage that causes HDD failure from drops, and power consumption drops significantly, extending laptop battery life. At under thirty-five dollars, it is among the most cost-effective performance upgrades for any computer. For anyone with a slow laptop that still has good hardware otherwise, a Kingston A400 installation is often the single best investment available.
